Car batteries wear out just like any other battery and need to be replaced. There are a couple of things Duluth vehicle owners should know when looking for a new car battery: one is cold cranking amps and the other is reserve capacity.

Let's start with cold cranking amps. This can be thought of as the power output used to start a cold vehicle engine. The number of cold cranking amps you need depends on your vehicle and where you live around Duluth, specifically how cold it is where you live. The two factors are that the colder an engine is, the more power it takes to turn the vehicle engine over to get it started. It has all that cold, sluggish oil to contend with. The other factor is that the chemical reaction in the battery that creates electrical energy is less efficient in the cold.

So the colder it gets in Duluth, more power is needed, but the available power drops.

If you live where it's cold, you need a battery with more cold cranking amps than you do where it's moderate or hot. You should always get at least as many cold cranking amps as the manufacturer recommends but may want to upgrade at Hansen's Auto Service Of Duluth INC. if you live where it gets real cold.

An important note: Batteries may also list the Cranking Amps – CA – number. It is the Cold Cranking Amps – or CCA – that is the important number here. CCA is the number to use in your comparisons.

Now with all this talk of cold temperatures in Duluth, it's important to note that heat is the real enemy of long battery life. In other words, the damage that's done over the hot summer months in Duluth shows up with the increased demands on the vehicle battery when the weather turns cold.

Now on to reserve capacity: It's a measurement of the number of minutes of reserve power the battery has at a given load. The number is more important these days because of parasitic drain. Parasitic drain is the battery energy that's used when the key is off. So the power drawn by the vehicle security system, the remote start system — even the power the vehicle computers require to maintain their memory.

Reserves are also needed when you make very short trips around Duluth. You're not driving long enough for the battery to recover the energy it used to start the vehicle engine.

So go with the minimum recommended by your manufacturer and upgrade if you need more. Talk with your friendly and knowledgeable Hansen's Auto Service Of Duluth INC. service advisor about options. If you need more from your battery, a larger capacity battery may be called for.
